There are tons of reports and rumors flying around that hackers have found a way to get in and clear out your account without needing your password, and bypassing Blizzards authenticator protection.
Apparently all they need is your username or battle tag.
Most reports seem to be from players lvl 50+
After peoples accounts were hacked they noticed a "chinese" name in their social menu under recently met players.
Accounts currently being hacked are being reported as showing the user as offline but their character showing as online.
Word of warning to all…. DO NOT join any games with people you do not know until Blizzard has sorted this out. DO NOT accept invites from people you dont know. DO NOT add people you dont know to your friends list.
